Planetary Powershift Transmission

Torque Divider

An exclusive Caterpillar designed torque divider allows the engine to respond quickly to varying workloads.

Torque Converter

The torque converter shields the driveline from sudden torque shocks.

Cooling System

Superior cooling in the most demanding work conditions.

Advanced Modular Cooling System (AMOCS)

Advanced Modular Cooling System (AMOCS) utilizes an exclusive two pass cooling system and increased cooling surface are to provide a more efficient heat transfer system than conventional systems.

Two Pass Cooling System

Two pass cooling system circulates coolant from the sectioned bottom tank up through one side of the cooling element and down through the other side returning it to the bottom tank.

Cooling Elements

The cooling elements are individual core modules that are connected to a sectioned bottom tank. There are nine steel fins per inch, brass tube construction within each core and no top tank to remove.

Servicing AMOCS

The servicing of the AMOCS can be performed without tilting the radiator guard. There is no need to remove or replace a major component as on single core radiators. Each core module can be replaced individually, saving considerable cost and repair time.

Undercarriage

The Caterpillar elevated sprocket undercarriage arrangements allow optimized balance for the best possible performance in each application.

Final Drives

Final drives and associated power train components are raised above the work area - isolating them from ground-induced impact loads, as well as implement and roller frame alignment loads - extending power train component life.

Sprocket Position

The sprocket position keeps sprocket teeth, bushings and final drives away from the abrasive materials and moisture - resulting in longer final drive gear and seal life.

Steering

Differential Steering

Differential steering maintains uninterrupted power to both tracks during turns through a hydraulically actuated planetary differential, and allows simultaneous one-hand steering and transmission control.

Finger Tip Control

Automatic Shifting

Bi-Directional Autoshift allows the operator to preselect a forward and reverse gear for directional changes. Auto-kickdown automatically downshifts the transmission when the engine lugs down to a predetermined RPM level.

Work Tools

Caterpillar work tools include a choice of dozers, rippers and winches designed for efficient, high production.

Blades

Choose from the S, SU, U or A blade for optimum production.

Ripper

The multi-shank parallelogram ripper lets you choose up to three shanks, depending on job conditions.

Winch

A single lever controls all winch functions - actuates both clutch and brake to improve operator efficiency.

Load Sensing Hydraulics

Adjusts attachment and hydraulic power to increase both operator and machine efficiency.

Hydraulic Power Requirements Continually Monitored

Load-sensing hydraulics utilize a feedback loop from the implement valve to the implement pump to continually monitor the hydraulic power requirements of the implement.

Hydraulic Pump Flow and Pressure Output

During normal blade or ripper corrections the hydraulic pump's flow and pressure output are regulated to only what is needed.

Lower Pump Requirements

Lower pump requirements can reduce engine power requirements for the hydraulics, making more drawbar power available for increased machine production, higher operator efficiency and increased fuel efficiency.
